I wear my Sonic Ions while riding and do not have any trouble with either wind noise or falling off. That said, it still depends on somethings. I, for instance, have the open fit domes which fit into my ear firmly and don't migrate out. That may or may not be the case for you. My top speed is a little more sedate than yours ranging from 10 to 20 mph. Wearing them during activities is a case by case thing because the parameters are different for every one.
